Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168382, here are decompositions:

  • 29 + 168353 = 168382
  • 59 + 168323 = 168382
  • 89 + 168293 = 168382
  • 101 + 168281 = 168382
  • 113 + 168269 = 168382
  • 239 + 168143 = 168382
  • 293 + 168089 = 168382
  • 311 + 168071 = 168382

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 168,382 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 168382 first appears in π at position 562,833 of the decimal expansion (the 562,833ordinal-suffix:rd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
